EU

EU stands for Energy Unit and is the unit of energy used by IndustrialCraft 2. It is similar to the SI unit of the Joule. EU can be created through various IC2 generators. EU can be stored in various blocks and items including BatBox, Energy Crystal, BatPack, and many more. EU can be transported through cables to power various IC2 machines.

EU/t means Energy Units per Tick. It is a derived unit that represents the energy transferred over time and is similar to the Watt. EU/t can be measured by an EU-Reader, giving the average EU/t flowing through a cable or block. EU will not flow if there is nothing to actively draw it.

An EU-Packet (EUP or EU/p) represents a discrete unit of energy. All machines and cables accept a maximum packet size and many devices (such as transformers and energy storage units) will only output energy in specific packet sizes. EU-Packets come in varying magnitudes from 1 EU to 1 million EU. The average value of all EU-Packets traveling through a cable per tick is the same as EU/t.

Note: Cables are rated for specific packet sizes, or EU/p, not EU/t. Thus a single cable may deliver power to or from multiple machines, even if all accept or produce the maximum packet size for that particular cable.
